I have another problem !!!
So far i made it that when i press space i spawn circles and they slowly go down. But when im in the last column and i press it spawns red circle, and when i press space again it spawns red circle again and it shouldnt !!! at every other column it normally spawns, first red then yellow and so on, but in the last one it doesn't do that...

here is the clip:

and this is Zeton's cpp file ( circles (red and yellow)) --- if i comment out the if(color == "red") ... else if(color == "yellow") ... section circles spawn on the last column normally, first red, then yellow and so on, but i dont know why !!! plus i need that function inside the if and else statements to be called.
